Description

The

Sensor Sewi KNX TH-L-Pr

captures brightness and motion in rooms. It meas-

ures the temperature and the air humidity and calculates the dew-point. Via the bus,
the indoor sensor can receive external values of temperature and humidity and pro-
cess them further with its own data to a total value (mixed value, e.g. room average).

All measurement values can be used for the control of limit-dependent switching out-
puts. States can be linked via AND logic gates and OR logic gates. Multi-function mod-
ules change input data as required by means of calculations, querying a condition, or
converting the data point type. In addition, an integrated control variable comparator
can compare and output variables that were received via communication objects.

Integrated PI-controllers control ventilation (according to humidity) and heating/cool-
ing (according to temperature). The

Sewi KNX TH-L-Pr

can output a warning to the

bus as soon as the comfort field, as per DIN 1946, is left.

Functions:

•

Brightness measurement

with

brightness regulation

•

Motion detection

•

Measuring the

temperature

and

air humidity

(relative, absolute), each with

mixed value calculation

. The share of internal measurement value and

external value can be set as a percentage

•

Bus message, whether the values for temperature and air humidity are within
the

comfort field

(DIN 1946).

Dew point

calculation

•

Switching outputs

for all measured and computed values. Threshold values

can be adjusted per parameter or via communication objects

•

PI-controller for heating

(one or two-stage) and

cooling

(one or two-stage)

according to temperature. Regulation according to separate setpoints or basic
setpoint temperature

•

PI controller for humidity

according to humidity: Ventilate/Air (one-stage) or

Ventilate (one or two-stage)

•

8 AND and 8 OR logic gates

, each with 4 inputs. All switching events as well

as 16 logic inputs (in the form of communications objects) can be used as
inputs for the logic gates. The output of each gate can be configured optionally
as 1-bit or 2 x 8-bit

•

8 multi-function modules

(computers) for changing the input data by

calculations, by querying a condition or by converting the data point type

•

4 manipulated variable comparators

to output minimum, maximum or

average values. 5 inputs each for values received via communication objects

•

Summer compensation

for cooling systems. A characteristic curve matches

the target temperature in the room to the external temperature and sets the
minimum and maximum target temperature values

Configuration is made using the KNX software ETS. The

product file

can be down-

loaded from the Elsner Elektronik website on

www.elsner-elektronik.de

in the “Ser-

vice” menu.
